Drinks with European guy (5)
I believe the answer is:
tease
'guy' is the definition.
(thesaurus)
'drinks with european' is the wordplay.
'drinks' becomes 'teas' (tea is a kind of drink).
'with' says to put letters next to each other.
'european' becomes 'e' (abbreviation e.g. EU).
'teas'+'e'='TEASE'
(Other definitions for tease that I've seen before include "Deride" , "Make fun of; comb wool" , "Rib, annoy" , "Banter, make gentle fun of" , "Make playful fun of (someone)" .)
